The swirling flow field in an internal cooling air system in which the fluid passes through an inducer, a hollow turbine shaft, and a cavity between two disks (referred to as a wheel space) is solved using computational fluid dynamics and the pressure fluctuations on the hollow shaft wall ...
The swirling flow field, including unsteady non-axisymmetric phenomena in a rotating hollow tur bine shaft, is solved using computational fluid dynamics. The three-dimensional compressible Navier-Stokes equations are adopted and discretized by an implici
One of such non-intrusive velocity measurement devices for swirling flow field determination is the particle image velocimetry (PIV). In one study, Almheiri et al. (2020) analyzed the swirling flow of water in a test section of diameter of 4.1 cm and length of 60 cm with a stereo-...
In this work, the swirling flow field induced by guide vanes was studied using electrical resistance tomography (ERT) and numerical simulations. The results show that the two-phase water and oil mixture moves in the same axial direction for this type of flow field, which is very unlike the ...

A computational fluid dynamics model, based on χ-ε turbulence model for the closure of steady turbulent flow, was used for the evaluation of the swirling flow field. Also a vortexing fluidized bed combustor(VFBC)cold model testing facility was designed, fabricated, and tested. Computations and...
When the vortex flow expands upon entering the combustion chamber, a central reverse flow field is generated (called vortex breakdown) in which the flame front can stabilize without attaching to the metal surfaces of the burner. Sign in to download full-size image 5.3. The EV burner principle....
